COMMERCIALLY slit coils can have often
have as much as 35% of their edges that
are not cut cleanly. This can be due to
many factors such as bad practices, poor
quality material and badly worn tooling. The
result of this is that edge presentation at the
welding point will be poor and welding heat
has to be increased to ‘melt’ more material,
excessive squeeze pressure also has to
be applied to avoid defects. These issues
will increase material and energy costs as
well as creating an excessively large inside/
outside welding flash that then has to be
removed. In summary a very bad situation.
STE’s Duratrim is a unique edge scarfing
system for welded tube mills. It enables the
manufacturer to trim and clean the steel coil
edges as it enters the tube mill prior to the
forming station. It is particularly effective for
aluminised material for automotive exhaust
systems.
This process helps realise significant
benefits: reduced welding energy; consistent
homogeneous weld integrity; reduced strip
width/costs; ability to weld more challenging
materials; reduced rejects; less OD/ID
welding flash (bead); less ‘splatter’ from
weld zone; consistent strip width leading
to fewer rejects; unit runs ‘dry’ without
emulsion; increases life of impedors and
OD/ID scarfing tools; increased yield and
correct all slitting problems.
It is a simple but effective design with a
unique method of shaving the strip edges.
This is due to the ‘floating’ design of the
Duratrim scarfing system
improves strip edge presentation
scarfing assemblies which allow the unit
to follow the path of the steel strip whilst
maintaining positive contact pressure on
the scarfing inserts. The system utilises
four sets of special scarfing inserts, which
remove material from the strip edges, top
and bottom. The inserts are supported and
kept in position by pneumatic cylinders (eight
in total), the pressure of which is adjustable
enabling different amounts of material to be
removed. All sets of inserts are mounted
on a floating mechanism ensuring constant
material removal even with movements in
the strip. The Duratrim is capable of running
up to 100m/min without cooling of the
cutting tools; speeds above this may require
emulsion cooling. Duratrim is simple to
install and set, requires only compressed air
to operate and is a low cost investment. It
offers considerable benefits over other more
expensive edge preparation systems and
will ensure a rapid payback on investment.
It can be mounted onto the mill forming bed
or ‘freestanding’ between accumulator and
forming station. It is easily able to withstand
cross welds (coil join sections) and will even
cope with damaged strip at the beginning or
end of a coil.
